  3. Agenda  Introduction  Sifting for the fictional town of Avalon  Sifting for the A12  Traffic modelling  AOB – forum feedback

  4. Sifting for fictional town

  5. Fictional town of Avalon Avalon is situated on the Arthurian motorway network. The section running 2 km either side of the town is almost 50 years old. The town has a rich history with an historic battleground, remembrance park of Camlann, Monmouth Area of Outstanding Natural beauty (AONB) and Nyneve Lake all near by. The economy is largely dependent on tourism and agriculture. Both of which depend on the local waterways. 5

  8. Identification of problems and objectives How? Avalon’s issues: • Desk based study of national and  Long journey times to the local policies and priorities motorway • Identification of study area  Large farming industry - • Analysis of current situation businesses are finding cost of • What the future looks like transport are affecting their growth.  Local roads frequently flood This work produces. • Key objectives based on analysis and  No road improvements for 50 engagement with statutory bodies. years 8

  9. Generating options  Avalon’s Town Council have previously commissioned route options  Lord Pendragon, a major landowner and farmer put forward a route last year  A number of local specialists from the council and government organisations were engaged to generate route options This work generates 20+ options 9

  10. The Options Sifting Process • ‘Sifting’ is the evaluation of many different options. • Key is that the options meet the defined objectives and a strategic fit . • Department for Transport Early Assessment and Sifting Tool (‘EAST’) is used to sift options. 10

  11. Shortlisting – part one • Routes that didn’t meet strategic What to look at… objectives • Route problems • Study objectives • Engineers and environmentalists • Scheme deliverability, look at options to identify the best feasibility and ‘route’ in each avoiding ‘environmental showstoppers’ affordability • This process identifies a short list of feasible better performing options 11

  12. Shortlisting - part two A pply the Treasury’s Case Model 1. Strategic case 2. Economic case 3. Management case 4. Financial case 5. Commercial case Review original objectives and enhance and apply 12

  13. Fictional town of Avalon - viable options for consultation Route generation and sifting is detailed in an Options Appraisal Report. 13

  14. What happens next Analyse the responses received and then undertake any additional technical work required Report the feedback received to the decision maker Should decision maker believe there is a compelling case for the scheme and a suitable option, a preferred route would be announced Further engagement with communities, land owners and stakeholders as the preferred route is developed and more technical work takes place, including environmental A statutory public consultation on the Preferred Route Further technical work and engagement, then submit an application for a Development Consent Order (Planning Application) Consent Order decision received If successful, construction would begin 14

  16. Stages of sifting create long list select options identify issues of options to 'shortlist for & objectives achieve options' consultation objectives

  17. Identifying issues and objectives Issues Objectives Congestion Improving user satisfaction Safety Making the network safer Resilience Supporting the smooth flow of traffic Reliability Encouraging economic growth Substandard junctions Delivering better environmental outcomes Poor provision for non-motorised users Helping cyclists, walkers and other vulnerable road users of the network

  18. Long list of options Using existing reports, technical workshops and objectives, a long list of options was created: • 5 options, including: • Implement high occupancy vehicle lanes Public transport • Upgrade existing rail routes and branch lines • Implement Bus Rapid Transit Collision reduction • 3 options, including: and incident • Implement safety measures such as “keep apart” chevrons and ban HGV overtaking management • Remove and divert at grade rights of way and /or improve at grade crossings Highways • 15 options, including: • Providing a new parallel offline route from junction 19-25 improvement • Review and rationalise junctions options • Road repairs

  19. Shortlisting of options - part one Long list shortened by applying objectives. The following were eliminated as they would not tackle all problems that need to be addressed:  Public transport options  Collision reduction & incident management measures  A number of highways improvement options

  20. Shortlisting of options - part two We then asked the following of the six remaining options:  Is it the right strategic fit?  Does it show value for money?  Is there a financial and commercial case?  Can it be delivered? This left 3 options

  21. Enhanced objectives We then undertook a review and enhanced and added to the initial objectives:  Supporting economic growth  A safe and serviceable network  A more free flowing network  An improved environment  A more accessible and integrated network  Customer satisfaction

  22. What happens next Analyse the responses received and then undertake any additional technical work required Report the feedback received to the decision maker Should decision maker believe there is a compelling case for the scheme and a suitable option, a preferred route would be announced Further engagement with communities, land owners and stakeholders as the preferred route is developed and more technical work takes place, including environmental A statutory public consultation on the Preferred Route Further technical work and engagement, then submit an application for a Development Consent Order (Planning Application) Consent Order decision received If successful, construction would begin 22

  23. Traffic Modelling

  24. Traffic modelling Identify problems and Development Scheme objectives for of 2016 traffic option an area model assessment Data Development of Collection future traffic growth models Stage 0 Stage 1 Outline Options Strategy identification Current p osition

  25. Data collection – existing vehicle movements Between April and June 2016 we commissioned a large number of traffic Braintree surveys across the area. Other data sources used Colchester include: Highways England’s  journey time and traffic Witham flow  Traffic data from the Chelmsford A120 study Mobile phone origin-  destination data Trafficmaster origin-  destination and journey time data

  26. Existing traffic capacity and journey time Up to 90,000 vehicles per day (two-way) Existing flows are over 100% Capacity Existing flows are over 85% Capacity Over 4,000 vehicles in each direction at the busiest locations Existing flows are under 85% Capacity B1018 A130 B1024 A120 Chelmsford Witham Kelvedon J19 J20a J22 J20b J21 J23 J24 J25 Hatfield Peverel Junction 19 - 25 Free flow journey time - 15 mins B1019 Typical peak journey time - up to 25 mins

  27. Traffic Model We are currently developing a new traffic model using the 2016 traffic data using Colchester computer software. The model Braintree reflects typical weekday ‘peak hour’ conditions. The model will allow us to study how traffic moves across the Chelmsford area, not just on the A12, but a A12 much wider area. Forecast models allow us to Brentwood Witham see how traffic might change in the future on the A12 and on local roads (with and without A12 the implementation of scheme options).

  28. Understanding scheme benefits The scheme will lead to significant improvements in traffic conditions throughout the wider area and not just on the scheme itself. We study this by developing a traffic growth ‘forecast’ model which tells us about traffic conditions in the future. Traffic modelling allows us to assess a number of different impacts and benefits across the entire study area including (but not limited to): Journey time savings • • Vehicle operating cost savings (lower fuel usage, reduced vehicle maintenance, etc.) Accident savings • These benefits can be turned into a monetary value then used to provide a “Benefit to Cost Ratio” (BCR) and subsequently estimate the Value for Money of the scheme. Any scheme must demonstrate Value for Money.
